Tullio Eugenio Regge (Italian: [ˈtulljo ˈrɛddʒe]; July 11 Red Wing shoes online, 1931 – October 23, 2014) was an Italian theoretical physicist Cheap The Kooples Dresses. He obtained the laurea in physics from the University of Turin in 1952 under the direction of Mario Verde and Gleb Wataghin, and a Ph.D. in physics from the University of Rochester in 1957 under the direction of Robert Marshak. From 1958 to 1959 Regge held a post at the Max Planck Institute for Physics where he worked with Werner Heisenberg. In 1961 he was appointed to the chair of Relativity at the University of Turin

. He also held an appointment at the Institute for Advanced Study from 1965 to 1979. He was emeritus professor at the Polytechnic University of Turin while contributing work at CERN as a visiting scientist. Regge died on October 23, 2014. He was married to Rosanna Cester, physicist, by whom he had three children: Daniele, Marta and Anna.
In 1959 2016 Bogner Cheap Sale, Regge discovered a mathematical property of potential scattering in the Schrödinger equation—that the scattering amplitude can be thought of as an analytic function of the angular momentum, and that the position of the poles determines power-law growth rates of the amplitude in the purely mathematical region of large values of the cosine of the scattering angle (i.e. , requiring complex angles). This formulation is known as Regge theory. Regge trajectory, a part of Regge’s theory which tries to explain slowly rising cross section of hadronic collisions at high energies, was first demonstrated at CERN for Intersecting Storage Rings (ISR).
In the early 1960s, Regge introduced Regge calculus, a simplicial formulation of general relativity. Regge calculus was the first discrete gauge theory suitable for numerical simulation, and an early relative of lattice gauge theory. In 1968 he and G. Ponzano developed a quantum version of Regge calculus in three space-time dimensions now known as the Ponzano-Regge model. This was the first of a whole series of state sum models for quantum gravity known as spin foam models. In mathematics, the model also developed into the Turaev-Viro model, an example of a quantum invariant.

He received the Dannie Heineman Prize for Mathematical Physics in 1964, the Città di Como prize in 1968, the Albert Einstein Award in 1979, and the Cecil Powell Medal in 1987.
In 1989, Regge was elected to the European Parliament as a candidate of the Italian Communist Party and served until 1994. Regge served as president of the Turin section of the Association for Research in Handicap Prevention (AIRH).
He was awarded the Dirac Medal in 1996, the Marcel Grossmann Award in 1997, and the Pomeranchuk Prize in 2001. The asteroid 3778 Regge has been named after him.
Regge theory, a theory of strong interaction phenomenology at high energies, and Regge calculus are named after him.

Bothe grew up in Chester, Virginia, and attended Thomas Dale High School discount Puma shoes outlet 2016, where he won the Gatorade Virginia High School Player of the Year and VHSCA Group AAA Male Athlete of the Year awards in both 2005 and 2006.
He played college soccer at The College of William & Mary, where he received numerous accolades, including VaSID All-State First Team Maje Sale, All-CAA Second Team , NSCAA All-South Atlantic Region Second Team and Scholar All-American Second Team honors.
Bothe also spent seven years in the Richmond Kickers club youth system, joining the club as a U-15 Elite player in 2002 before graduating to the Richmond Kickers Future USL Premier Development League team in 2006.
Bothe turned professional in 2010 when he signed with the Richmond Kickers of the USL Second Division, and in doing so became the first player to rise from the youth to the pro ranks within the club. He made his professional debut on April 17, 2010 in a league match against Harrisburg City Islanders.

David Seymour (born Dawid Szymin; November 20, 1911 – November 10, 1956), or Chim (pronounced shim, an abbreviation of the surname “Szymin”), was a Polish photographer and photo journalist known for his images from the Spanish Civil War, for co-founding Magnum Photos with Henri Cartier-Bresson, Robert Capa, George Rodger and William Vandivert , and for his project “Children of War” with UNICEF that captured the plight of children in the aftermath of World War II. He became president of Magnum after Capa’s death in 1954 and held this post until his own death in 1956 by Egyptian machine-gun fire in the aftermath of the Suez crisis.

Chim was born to Polish Jewish parents in Warsaw in 1911. David had a sister, Eileen, who was three years older. Their parents were Regina and Benjamin Szymin, a respected publisher of Yiddish and Hebrew books. In 1914 Chim and his parents emigrated to Odessa just as World War I had begun. In 1919 they returned to Warsaw. Chim studied graphic arts in Leipzig and then traveled to Paris, France to study at the Sorbonne.
It was while Chim was studying at the Sorbonne in Paris that he became interested in photography. Chim began working as a freelance journalist in 1933. His first “credited” published photograph appeared in 1934 in the magazine “Regards.” Between 1936 and 1938 Chim covered the Spanish Civil War (alongside colleague Robert Capa) and other international political events. In February 1935 Chim was sent to Spain by Regards to report on crucial issues there. Twenty five of his stories on Spain ended up being published in Regards. In 1939 he covered the Loyalist Spanish war refugees on the S.S. Sinai to Mexico and then later in the year he arrived in the United States. Chim was in New York when World War II broke out in Europe when Nazi Germany invaded Poland, Chim’s birthplace. In 1940 he enlisted in the United States Army, serving in Europe as a photo interpreter during the war. In 1942 he became a “naturalized” citizen of the United States, the same year that his parents were killed by the Nazis. Chim photographed for Life, along with Look, Paris-Match and Regards. In 1948 he received a commission through UNICEF and traveled to Austria, Hungry, Italy, Poland and Germany to document the plight of World War II refugee children. Inge Bondi, Chim scholar, said: “Chim’s heart had always gone out to children, and they reacted to him with complete acceptance. They seemed oblivious of him bogner jacket, but he noticed every little movement, every little pain world cup soccer jerseys 2016, every little pleasure. There is no artifice, no bravura of lighting expertise in Chim’s photographs of the children. They speak simply from his pictures, as if alive. This intellectual, so adept at analyzing the most complex political situations, so comfortable photographing heads of state, produced his greatest photographs to help children in need Karen Millen Outlet Online 2016.” Between 1949 and 1955 Chim traveled extensively throughout Europe and Israel fulfilling assignments for major publications in Europe and the United States.
In 1947, Chim co-founded the Magnum Photos photography cooperative, together with Robert Capa and Henri Cartier-Bresson, whom he had befriended in Paris in the 1930s. As Inge Bondi, Chim scholar, stated: “Photojournalism was about to enter a golden decade. Television was not yet available to broadcast world events, and editors and the public were eager for news, from which they had been cut off during the fascist years and war years.” After Capa’s death in 1954, Chim became president of Magnum Photos. He held that post until his death on November 10, 1956.
On November 10, 1956, Chim was killed while driving to photograph an exchange of wounded soldiers at El Quantara (along with French photographer Jean Roy) by Egyptian machine-gun fire four days after the armistice of the 1956 Suez War. Chim’s work remains available by way of Magnum Photos and his estate is managed by nephew Ben Shneiderman and niece Helen Sarid.
Chim’s reputation for his photos of war orphans was magnified by his later work in photographing famous people of his time. These included:
Chim’s work is held in the following collections:

A Diet Coke and Mentos eruption’ (alternately ‘ Diet Coke and Mentos geyser or Mentos eruption) is a reaction between the carbonated beverage Diet Coke and Mentos mints that causes the beverage to spray out of its container

. The gas released by the candies pushes all of the liquid up and out of the bottle for a huge explosion. Lee Marek and “Marek’s Kid Scientists” were the first to demonstrate the experiment on television in 1999. Steve Spangler’s televised demonstration of the eruption in 2005 went viral on YouTube ted baker dresses 2016, launching a chain of several other Diet Coke and Mentos experiment viral videos.

In the 1980s, Wint-O-Green Life Savers were used to create cola geysers. The rolls of candies were threaded onto a pipe cleaner and dropped into the soft drink to create a geyser. At the end of the 1990s the manufacturer of Wintergreen Lifesavers increased the size of the mints and they no longer fit in the mouth of soda bottles. Science teachers found that Mint Mentos candies had the same effect when dropped into a bottle of any carbonated soft drink.
Lee Marek and “Marek’s Kid Scientists” performed the Diet Coke and Mentos experiment on the Late Show with David Letterman in 1999. In March 2002, Steve Spangler, a science educator, did the demonstration on KUSA-TV, an NBC affiliate, in Denver, Colorado. The Mentos Geyser Experiment became an internet sensation in September 2005. The experiment became a subject of the television show Mythbusters in 2006. Spangler signed a licensing agreement with Perfetti Van Melle, the maker of Mentos, after inventing an apparatus aimed to make it easier to drop the Mentos into the bottle and produce a large soda geyser. The Amazing Toys, Spangler’s toy company, released the Geyser Tube toys in February 2007. In October 2010, a Guinness World Record of 2,865 simultaneous geysers was set at an event organized by Perfetti Van Melle at the SM Mall of Asia Complex, in Manila, Philippines. This record was afterwards beaten in November 2014 by another event organized by Perfetti Van Melle and Chupa Chups in Leon, Guanajuato, Mexico where 4,334 Mentos and Soda fountains were set off simultaneously.
The structure of Mentos is a significant cause of the eruption because of its nucleation sites. The surface of the mint Mentos is covered with many small holes that increase the surface area available for the reaction (and thus the quantity of reagents exposed to each other at any given time), thereby allowing carbon dioxide bubbles to form with the rapidity and quantity necessary for the “jet”—or “geyser”—or eruption-like nature of the effusion. This hypothesis gained further support when rock salt was used as a “jump start” to the reaction. Tonya Coffey, a physicist at Appalachian State University in Boone, North Carolina, confirmed that the rough surface of the Mentos candy helps speed the reaction. Coffey also found that the aspartame in diet drinks lowers the surface tension and causes a bigger reaction, but that caffeine does not accelerate the reaction. The geyser reaction will still work even using sugared drinks

, bubbles form around the surface of the mints and rise to the surface of the liquid. In addition, the density of Mentos is greater than the density of the drink, which results in the candy sinking. These two factors combined create the blast.
The potassium benzoate, aspartame, and carbon dioxide gas contained in Diet Coke, in combination with the gelatin and gum arabic ingredients of the Mentos contribute to the formation of the foam.
